<div>Hello All</div>
<div> </div>
<div>I am very new to cisco voip and just starting to learn alittle. Through my studies I was left with a question about h323 security. I am initially setting up a cisco 2801 router as a gateway for my CUCM 7.0. I have it setup but the though came to mind is there anyway to set up any kind of authentication between the CUCM and the cisco 2801 router? If a malicious user put up there own CUCM on the lan they could infact use my gateway to make calls without such authentication? Sorry if I am missing something obvious.</div>
